Women who will fulfill the study inclusion and exclusion criteria and agree to be included in the study will be randomized assigned to receive either an intravenous injection of 10mg metoclopramide (Group 1) or the same volume of placebo, i.e. 0.9% sodium chloride (Group2). Randomization will be achieved using computer generated randomization sequences. Allocation will be in 1:1 ratio. Record of group allocation will be maintained by a resident physician whose responsibility is randomization and drawing up the injection, but has no direct involvement in the intrapartum decision making.
